HEAD CONSTRUCTION FOR ELECTRIC LAMPS.

Specification of Letters Patent.

Patented Oct. 12, 1920.

Application filed September 17, 1917. Serial No. 191,867.

To all whom it may concern:

Be it known that I, MORRIS OZLEK, a c1t1- zen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements in HeadConstructions for Electric Lamps, of which the following is aspecification.

One object of my invention is to so construct an electric lamp head thatthe lamp sockets can be securely attached and, so that the shade can beeasily and quickly placed thereon and removed therefrom without theassistance of any clamping means.

A further object is to so design my invention that it will be durableand can be quickly made and assembled.

These objects, and other advantageous ends which will be describedhereinafter, I attain in the following manner, reference being had tothe accompanying drawings in which- Figure 1 is an elevation partly insection showing my improved lamp and how the shade is mounted thereon. V

Fig. 2 is a fragmentary section taken on v the line 2-2 of Fig. 1.

Fig. 3 is a top plan view of my invention as shown in Fig. 2 with thetop sectlon removed.

Referring to the drawings, 1 represents a standard which is preferablymade of wood and which may have any form of base, since the specificconstruction of the latter does not form a part of my invention.

' The upper end of the standard 1 is made cylindrical as shown at 2 tofit in a cylindrical bore 3 in a base section 4 of a head 5, preferablymade of wood. The standard is also provided with a collar 6, preferablymade integral therewith which forms a support for the bottom of thesection 4.

The section 4 has an annular flange 7, at the top, of relatively greaterdiameter than the bottom portion of said section. The top surface of thesection 4 has a. recess 8 depending therein and a hole 9 communicateswith this passage and with the cylindrical bore The standard 1 is madehollow and the electric supply wire 10 for the lamp extends throu h thehollow standard 1, hole 7 9, and into the recess 8.

The head 5 has a top section 11 and is of a diameter considerablygreater than the largest diameter of the section 4. The top section 11is made comparatively flat a clearly shown in Figs. 1 and 2 and has ashallow annular cavity 12 cut in its bottom surface 13. The upperportion of the annular flange 7 of the bottom section 4 fits with- 1nthe cavity 12 and screws 7 extend up.- wardly through the flange 7 intothe section 11 as clearly shown in Fig. 2. -Thus, the bottom section andtopsection are detachably secured together and the heads of the screwsbeing inverted, are practically invisible.

The section '11 also has a recess 14 extending inwardly from the cavity12 and which co-acts with the recess 8 to provide a chamber 15 withinthe head. The section 11 has a thin circumferentially extending rim 16,the bottom of said rim being coincident with the bottom surface 13.

The rim 16 is comparatively wide and as illustrated is located aconsiderable distance below the top surface 17 of the section 11. Thus,a secure and rigid support is produced for a ring 18 supporting theshade 19. The ring 18 is connected to the shade and forms a part of itsframe as clearly shown in Fig. 1.

Threaded sleeves 20 extend through the section 4, and at their innerends are provided with nuts 21 which engage and have their bearing uponthe tapered side 22 of the recess 8. The outer ends of the sleeves 20form the support for the electric sockets 23. The electric wire 10 ishoused within the chamber 15 and has branches 24 and 25 which extendthrough the chamber 15 and downwardly through the sleeves 20 to therespective sockets 23 to supply the electric current to the electricbulbs 26.

The edge surface 27 of the top section 11 is frusto-conical in shape andtherefore has a slight upward taper to facilitate the placement of thering 18 thereover and so that it rests snugly between the surface 17 andthe top of the rim 16. Furthermore by making the surface 27 offrustro-conical shape, it will serve to support lamp shade securingrings 18 of various diameters and the weight of the lamp shadesupporting ring engaging the tapered surface will bind the ring to thetop section of the head and thereby prevent the swinging of the shade 0nthe head. By providing the extended rim 16, any lamp shade supportingrings which are of greater diameter than the largest diameter of thesurface 27 can be supported by said rim 16.

The internal diameter of the ring 18 is preferably made equal to thegreatest diameter of the section 11 above the rim 16.

However, if the diameter of the ring varies either smaller or greater,the top section is capable of securely supporting the same in View ofthe large diameter of the rim 16 and the gradually tapered edge surface27.

To detach the top section 11, it is merely necessary to remove thescrews 7 when the entire contents of the chamber will be exposed forrepair or any other purpose desired. It will thus be noted that the nuts21 securely hold the sleeves and sockets in position and there'are nomeans necessary for securing or clamping the shade to the head.

While I'have described my invention as taking a particular form, it willbe understood that the various parts of my invention may be changedwithout departing from the spirit thereof, and hence I do not limitmyself to the precise construction set forth, but consider that I am atliberty to make such changes and alterations as fairly come Within thescope of the appended claim.

Having thus described my invention, what I claim as new and desire tosecure by Letter Patent is: p

A lamp head includinga lamp shade supporting top, said top including afrustoconical portion terminating at its bottom in an annularlyextending rim, the outer peripheral of said frusto-conical portionserving to support lamp shade securing rings of various diameters due tothe frusto-conical shape of'said top portion, said peripheral surfacebeing of comparatively great depth relative to the thickness of saidlamp shade securing rings and extending at such steep angle that thelamp shade securing rings cannot shift laterally when resting thereon,said rim serving to support the securing rings oflamp shades of largerdiameter than the largest diameter of said frusto-conical portion;substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. V
